Purpose:
To analyze the effect of porcelain dental restoration combined with labial surface root filling for the anterior teeth.
Methods:
One hundred cases with anterior teeth protrusion treated in our department from January 2010 to January 2014 underwent porcelain dental restoration combined with labial surface root filling. The measurements in cephalometric X-ray films before and after treatment were compared, and porcelain dental appearance and function were evaluated. The data was statistically analyzed with SPSS18.0 software package.
Results:
After treatment, U1-SN, U1-X, U1-Y were significantly lower than before treatment (P<0.01). U1-L1 was significantly higher after treatment (P<0.01). The incidence of gingivitis after treatment decreased significantly (X(2)=16.2749,P=0.0000<0.01). The excellent rate of outline of porcelain teeth after treatment, correction of protruding anterior teeth, fitting with adjacent teeth and alleviation of deep overbite and deep cover was 96.00%, 95.00%, 98.00% and 91.00%, respectively.
Conclusions:
Porcelain dental restoration after root canal treatment can effectively improve anterior teeth protrusion and increase the aesthetic appearance, which is worthy of clinical application.
